what is the brush that gives you that feeling of "luxury" regarding its price?

Mine is the Vie Long 16910 silvertip brush with a loft of 47mm.This brush is velvety soft,but with a nice backbone and perfect flow and very well packed with premium silvertip hair..I would consider it the most "luxurious feeling" one that I have now.

The Semogue LE 2010 is another one that gives me that "luxurious feeling".

For me the luxuriousness - i.e. how much the brush makes me feel spoiled and pampered - is mainly a function of the loft and hair quality. Previously, before I sold it, I would have said that my Plisson Size 20 in HMW, with a loft of 68mm, was the most luxurious. Now it probably is my Somerset Simpson Polo 14 in Extra Super (Manchurian), with a loft of 70mm.

Vulfix 2236 Silvertip. No question about it, this brush is big and crosses the line on the floppy end of the scale but it's so soft you almost can't tell it's touching your face. On the other end of the scale, I received a Semogue 830 recently and it is NOT completely broken in. I've followed most of the directions listed on the various forums on how to break a Boar in but that is about the equivalent of perhaps a dozen shaves. The tips have definitely split and the brush has splayed (bloomed). I'm 100% sure it will continue to improve but I don't ever seeing this being in same "luxurious category" that I associate with the big Vulfix. These would be the two extremes in my collection of about a dozen brushes with Simpson's, Kent and a few others in the middle of the scale. I have several more SilverTips including a Super SilverTip from TGN that I really like even more than the luxurious Vulfix (read more backbone).

Well you asked luxurious, not best all around or most effective, so to my mind as much as I love my boars, luxurious rules out the boars. They are xcellent brushes but luxurious doesn't bring them to mind.

To me luxurious is cloudlike and soft, a delicate caress for the skin as it does it's work.

Probably my Rooney 3/1 Silvertip, but it's difficult to choose. It has luxuriousness and a decent size. It's like using a cloud to lather with.

I just went to the cabinet to double check. The new Commodore x1 Best is pretty darn luxurious, but the Rooney just has "more". That is, it's a bigger area of "soft and delicate caress". The Commodore is definitely luxurious though.
